摘要
本项试验研究揭示出播区选择与地貌、地类的内在联系,分析了各植物种在不同地类上的成苗、生长情况,筛选出适宜的草种组合及单位播量。采用棋盘式或重复式作业,显著地提高了落种、成苗均匀度。两用草场的建立,从根本上改变了单一的沙打旺草场景观,取得了显著效益。
This study points out the internal relations of sowing-area selection and mixed sowing re- sults,and the air seeding effect of various earth's surface through analys.It puts forward the se- lection of grass seed and seed mixtures as well as the perha sowing quantyties.The mixed seed air seeding technique of chessboarding and repeating model are applied to the experiments which evidently increased the even rate of broadcasting of seeds and the proter distribution of seedlings. Such broadcasting has changed the landscape of simple prairie milkvetch in a large scale and obvi- ously beneficial.
